Major League Baseball has begun the process of interviewing players linked to the defunct Biogenesis anti-aging clinic in South Florida, CBSSports.com reports.

And "at least some" suspensions are likely to emerge from the probe, according to the report.

About 20 players, including the New York Yankees' Alex Rodriguez and the Milwaukee Brewers' Ryan Braun, have been linked to Biogenesis. Braun and A-Rod have not been interviewed yet because MLB officials want to make sure they have gathered sufficient evidence before confronting the two superstars about PED use, the report says.

Anthony Bosch, who was the head of Biogenesis, has agreed to cooperate with MLB's investigation. The clinic was accused in January by the Miami News Times of providing banned performance-enhancing drugs to players.

CBSSports.com reports "there is some suggestion" MLB officials believe the Joint Drug Agreement could allow it to announce suspensions before any appeals because the player names already have been made. The players union insists any suspensions must await the full appeal process.

Other players whose names have been tied to Biogenesis include the Washington Nationals' Gio Gonzalez, the Toronto Blue Jays' Melky Cabrera and the Texas Rangers' Nelson Cruz.
